Editing a Static Image Within A Page (1 post)

Hi! This may be a new question, however I did not even know where to start asking.

I have created a theme at http://msasia.brocknunn.com I have included an image in that page that needed to by dynamic. To accomplish this, I used the featured image function. However, I am sure this is not semantic with standards.

How would I best make a static image within a page template editable within that pages composition screen? I would really appreciate any help you guys could lend in this!
